ESRI Data & Maps 2009 Update Data Distribution Application (DDA)


Included on this disk is the Data Distribution Application (DDA), which is intended
primarily for converting the Data & Maps vector data from Smart Data Compression 
(SDC) format to shapefile format.  The SDC data can first be viewed in the DDA 
viewer by opening the provided ArcGIS map document (mxd) or AXL files, or by adding
in the individual SDC files.  After panning and zooming to the area of interest, 
all data layers checked on in the table of contents can then be extracted to 
shapefiles for the current map extent.

The \DDA folder on this disk contains two versions of the application: DDA_Arc.exe
for users with ArcGIS installed, and DDA.exe for users without ArcGIS installed.
Please see DDA_Help.htm for instructions on using both versions.

Important: Data extracted from any Data & Maps SDC file will still be governed by
the redistribution rights of the source SDC file.  Please review the Data & Maps
Redistribution Rights table before redistributing any of this data.  This table can
be found in the ESRI Data & Maps module of the ArcGIS Desktop Help, or through the
help.htm file located at the root level of this disk.
